Car battery charge state determination unit having set battery current rate variation and voltage/electrolytic temperature measurement inputting estimator providing charge state estimate

摘要

The charge state determination mechanism has a unit (1) charging the battery current rate in a set way, a voltage measurer (2) at the battery wires and a measurement of the battery electrolytic temperature (3). The three sets of information are used by an estimator (4) to determine the battery charge state.
